Incidence of Syphilis and its Diagnosis

Overview

Syphilis is a general chronic disease caused by bacteria from the family Spirochaetaceae, genusTreponema. Pathogenic representatives of the genus include, due to the marked agreement of DNAsequences (more than 90%) a crossed reactivity of serological tests. The increase in incidence of syphilisin the Czech Republic during the last decade of the 20th century puts increased demands on precision,early character and reliability of diagnosis. In addition to direct examination methods for uptake ofthe pathogenic organism in particular in direct diagnosis of the antibody response in serum as well ascerebrospinal fluid are decisive. On their selection depends the success when assessing the disease inthe population and in particular the most carefully investigated groups - blood and organ donors,pregnant women, neonates.
